Zhenbei city is already familiar with how to enslave dog headed people and goblins. Select some dog headed people and goblins from these slaves and give them better treatment. These vested interests will help Zhenbei City crush other slaves.

Tens of thousands of people work together on the construction site, and the progress of the project is still good. The wall of Jinghu city is built with rammed earth, with a height of only six meters. The higher the rammed earth wall is built, the larger the soil layer below. The work quantity of ten meters is more than twice that of the six meter high wall.

The six meter high wall can block most of the wasteland monsters. Even if you build it to ten meters, you can't block the rest of the six meter wall. Therefore, it is difficult to build a six meter high wall with rammed earth.

The base of the city wall uses rock. Su Lun directly uses the magic of turning mud into stone to convert the rammed earth base into rock. The quantities of the wall cornerstone with a circumference of four kilometers are not small. Fortunately, it is not built at one time.

The rammed earth used in the city wall is not used casually. The excavated earth needs to be screened first, pick out the stones and sundries inside, and then steam the earth. This is to kill grass seeds, insect eggs, etc.

Then use the steamed mellow soil to tamp layer by layer. The wall made in this way is not as hard as rock, but it is also very hard.

Su Lun was looking at a historical record of ancient city building in his previous life. Among them, there was a city called Tongwancheng. In order to build this city, glutinous rice juice, white silt, sand and hydrated lime were mixed with hydrated soil in a certain proportion and rammed together.

What makes people feel more numb is that the supervisors of the city are strict. During the acceptance, the soldiers are asked to stab the wall with an iron cone. If they can stab an inch into the wall, they will kill the workers who built the wall and fill the body close to the wall. If they can't stab in, they will kill the soldier. So that the city became a famous strong city at that time, that in the previous life thousands of years later, most of the ruins of Tongwan city were still preserved.

Of course, this strong city did not keep the dynasty. Nine years after the construction of Tongwan City, it was occupied by other countries.

Naturally, the rammed earth wall of Jinghu city will not be so extravagant. Sulun does not have a lot of glutinous rice to build the city, but a batch of lime is transported from the north city of Zhenbei, and then lime and steamed earth are mixed in a certain proportion to build the city.

While building the city in Jinghu City, the soldiers were also not idle. Although Jinghu was cleaned, the surrounding tribes still migrated here. In this way, these soldiers can not only train troops, but also continuously provide slaves for Jinghu city.

Su Lun didn't go there except after he took these soldiers to clean up several tribes a few days ago. The battle at this level was too simple and not challenging. Su Lun directly left it to the soldiers to deal with it. Then he asked the craftsmen to build a boat for him and go fishing on the mirror lake.

But his leisurely life was soon broken.

"You said wolves attacked the slaves in Jinghu city?" Su Lun handed the two fish to the bodyguard next to him.

"Yes, sir, and more than once." the drow elf nodded and continued, "at first, we thought it was some wild wolves or other beasts who took advantage of the slaves to attack, but these days, sneak attacks have occurred continuously."

"Did you find the wolf or beast that attacked?" Suellen asked with a frown.

"Sir, we have launched all scouts to look for it, but there is no news yet."

"Call some scouts from the north town to expand the search scope. I don't believe those beasts will suddenly appear and disappear." Su Lun said with cold eyes.

"Yes!"

"At the same time, send some more soldiers to the construction site of Jinghu City, tell the workers and slaves not to act alone, and report any abnormalities immediately."

Under Su Lun's order, the north town quickly dispatched a group of scouts. The official Aton, led by him, increased scouts and expanded the scope of investigation again.

But just after the order was issued, Jinghu city was attacked again!

And this attack was more eye-catching than any before, because this time not only some slaves and workers lost their lives, but also the soldiers of Zhenbei city sent by sulun to guard Jinghu city.

Four gunmen in the North Town died under the attack of wild animals. Moreover, the continuous deaths have seriously affected the construction progress of Jinghu city.

It's already very serious. Here in Jinghu City, the soldiers in the North Town cleaned up so many tribes that no soldiers died. Unexpectedly, they were killed by some wild animals.

Suellen's face was as cold as ice.

At first, Su Lun thought it was just an ordinary beast attack. Now four soldiers in Zhenbei city have died. Since Zhenbei City defeated the orcs, there are still people or other species who dare to attack Zhenbei city in this wasteland. This is challenging the bottom line of Zhenbei city.

Suellen is going to give these guys the hardest blow.

The construction of Jinghu city could not be stopped, so sulun sent some barbarian warriors and heavy armor long spearmen to guard. The strength of these barbarian warriors and heavy armor long spearmen was much stronger than ordinary soldiers. With these soldiers to guard, the attack was finally stopped.

The beasts that attacked should be aware of the strength of these barbarian warriors, so they did not continue to sneak attacks. The barbarian Tomahawk warriors who reached the third-order professional are powerful. These barbarian warriors who grew up after cruel and bloody fighting are the elite of the elite.

Although they like to go berserk and don't listen to the command in battle, they still have strong prediction of danger and have the talent of [intuitive evasion]. Although barbarians rush after berserk every time, in fact, there are not many who can really cause damage to them.

On the one hand, barbarian warriors are sent to guard, on the other hand, additional scouts are sent to investigate the surroundings.

Jinghu city construction site.

The workers began to be busy again. The fastest section of the city wall had been built to a height of three meters. A large number of slaves said that the prepared steamed soil would be transported up, and then tamped a little bit.

A small official in charge of building this section of the wall hurried over.

"Lord!" the person in charge of the construction of the city wall, who was in his thirties, came to him and bowed.

Suellen didn't stop and waved to them to get up. "Where was the attack? Show me!"

"Please follow me," the official said respectfully.

Near the construction site of the city wall, there was a wooden house. The party quickly walked past. This should be a place for the steward and the soldiers to rest.

Soon the party came to the house. In the small room, the bodies of four long gunmen were placed aside.

Sulun's face was cold, and he went forward to lift the white cloth off the body, revealing some ferocious bodies below. The body was still intact on the whole, with ferocious wounds. The iron armor was torn open, and the blood and flesh on the neck were blurred.

"The claws are sharp and like sneak attacks." after looking at the body for a while, Su Lun said in a deep voice: "although the defense of the inlaid iron armor is not as good as the iron armor, the strength of the beast should be great if it can destroy the inlaid iron armor to this extent."

"Ordinary beasts don't have such power, and these soldiers didn't even fight back. Obviously, they are good at camouflage and sneak attack, and they are very fast. Four soldiers died suddenly in a short time, and the attacker may not be one."

"It seems that we have some Warcraft here."

Su Lun is not very worried about Warcraft. Although Warcraft has strong strength and magic, it is very dangerous, as long as it can kill Warcraft, the income is also very high. The meat quality of Warcraft has some magical effects. The fur of Warcraft is valuable, and there are other things. In short, Warcraft can be called a treasure all over.

So many times, humans will organize people to hunt Warcraft. The industry is much more dangerous than mercenaries.

There are a lot of Warcraft in this world. Some Warcraft are bred from generation to generation, and some Warcraft are the result of the variation of ordinary beasts. The mutated beast may become larger, or have some ability to control elements, or both. Su Lun is not worried about Warcraft. Only those Warcraft dare appear in front of him, he is confident to kill these Warcraft.

As a legendary strong man, he has this confidence.

After simply eating some food, Su Lun discharged more scouts for investigation, while he himself stayed on the construction site and waited quietly.

Soon the scouts came some new news.

Some wolves were found in the forest in the northeast of Jinghu Lake, but these wolves were ordinary beasts. Soon night fell, and all workers and slaves began to return to the camp. Some slaves could only live behind the wall of Jinghu city because they could not live in the camp.

There used to be night shifts, but since the attack, night work has been cancelled.

If there are barbarian warriors, those attackers will no longer appear. Obviously, they have a high command, and it is not easy to catch them. If the barbarian warriors are kept guarding here, it is likely that they will not appear. Suellen doesn't want to keep the barbarian warriors here.

So he planned to send the barbarian warrior back, and he stayed here himself until the attackers appeared.

Let the barbarian warriors evacuate. Sulun hid in a leeward place behind the city wall and closed his eyes to sleep. As time passed, the attacker did not appear. Suellen didn't rest. His current physical quality won't have any problem even if he doesn't sleep for several days.

The night is getting deeper and deeper. The night wind blows and brings bursts of whine. Some campfires in the camp have been gradually extinguished. The time is close to two o'clock in the morning. This is the most sleepy time for people and the most lax time for defense.

Just then, sulun, who had closed his eyes, suddenly opened his eyes, and a flash of thunder flashed from his eyes.
